This invention relates to cashregisters and like machines, and more particularly refers to improvements in the printing mechanisms,

for such machines. Printing mechanism adapted to deliver two or more impression blows during one operation of the machine are generally designed to 'posltlvely retract the impression hammer or hammers prior to releasing said hammer or hammers, to make each impression.

As such printing impressions must be made in very rapid succession, the mechanical recooking of the hammer to its fully retracted position after the first impression is made in order to effect the second impression, requlres in a machine having a short cycle of operation.

To effectthe delivery of successive hammer blows on a single operation, utilizing a single hammer, and overcome the above mentioned and other objections, the following improved printing mechanism is provided, which effects two impression blows from a single hammer WltllOllt necessitatmg the retraction ofthe hammer operating means intermediate 130 such impressions.

It is, therefore, an object of this invention to provide a cash register or similar accounting or calculating machine with a printing mechanism adapted to print twice on the record material during one operation of the machine, with but one retraction of the impression hammer operating means. v

Another object is to provide a printing hammer with a plurality of operating means,

each of which is provided with an individual detaining device, a common means being pro vided to retract the operating means and to trip the detaining devices to release the op erating means successively.

With these and incidental objects in View, the invention includes certain novel features of construction and combinations of parts, the essential elements of which are set forth in appended claims and a preferred form or embodiment of which ishereinafter described 1928. Serial No. 294,492.

I General description The printing device illustrated herein is adapted for use inconnection with a cash register of conventional design, butby sl ght change, may be used ona great many types of cash registers and accounting machines now on the market. 7 A single impression hammer is provided to takeimpressions from the types set up, and

sions will not be made in the same place, mechanism is provided to feed the record material, or the slips, as hereinafter referred to, between impressions.

The printing hammer is normally held in its retracted position from which, at the proper time, and by mechanism now to be described, it is driven against the types to take the first impression on the record material. Immediately after the first impression has been made, the hammer is part way retracted towards its normal position, and, from its partially retracted position, is again driven against the types to take the second impression on the record material. After the second impression has been made, the hammer is again fully retracted, and held in such position preparatory to the next operation of the machine.

Suitably journaled type wheels or carriers 30 (Fig. 1), one only being shown, are positioned adjacent to one side of a chute 31, the outer end of which extends to a point outside the cabinet of the machine conveniently located for the insertion and removal of sales sli s 20.

' nd although, in this illustration, the invention is shown adapted to print on insertable record material, as sales slips and the like, it is obvious that the invention is equally applicable for use in printing upon detail strips, issuing checks or other record material, a supply of which may be contained within the cabinet.

- The type carriers 30 may be set or adjusted in any suitable manner, and the chute 31 is conveniently supported in any manner (not shown) between the printer side frame 32 and an outer bracket plate 33 (Fig. 8) spaced apart therefrom.

An ink ribbon 34 (Fig. 1) alternately wound on and unwound from suitably journaled rolls 35 and 36 passes around curved guards 37 and 38 housing the type carriers 30, one strand of the ink ribbon lying between the type carriers and the chute and extending across the aperture 39 in the chute.

Suitable means, not shown, reverses the ink ribbon at need.

Pita-ting hammer mechanism The impression mechanism is located on the opposite side of the chute 31 from the type carriers 30, and includes a channelled bar 45 (Figs. 1 and 3 to 8) fastened to a yoke 46, a platen 47 being seated in the channelled bar, and adapted to pass through an aperture 48 formed in the chute 31 opposite the type carrier to effect the imprint of amounts and other data on the inserted record material.

The arms 49, 50 of the yoke are journaled on a stud 51 supported between the printer side frame 32 and the printer bracket plate 33 (Fig. 8).

A light spring 52 connected to a rod 53 eX- tending between the arms 49, 50 of the yoke, tends to return the hammer to and hold it in its retracted position, the spring pressing the rod 53 against the longer arms of a pair of hammer-operating elbow levers and 61, pivoted side by side on the stud 51 with their longer arms extending over the rod 53.

A hammer restraining and restoring bail carried by arms 66 and 67 fast on a shaft 68 journaled in the printer side frame 32 and in the printer bracket 33, normally lies in the paths of the shorter, inclined arms 69 and 70 of the elbow levers 60 and 61 to hold the latter in their fully retracted positions against the tensions of their drive springs 71 and 72 respectively, which tend to rock the inclined arms 69 and 70 and their drive levers 60 and 61 counter-cloclnvise. Light springs 7 6 and 77 (Fig. 8) press hooked detents 78 and 7 9 pivoted on the shaft 68, against the ends of the long arms of the hammer-operating clbow levers 60 and 61, respectively, to latch the latter in their cocked or set positions. The restraining bail 65 normally takes the strain of the strong springs 71 and 72, so that a slight clearance (see Figs. 3, 4 and 5) exists between the long arms of the operating elbow levers 60 and 61 and the hooked ends of the respective detents 78 and 79.

Means to hold the hammer restraining and restoring bail 65 in and restore it to its normal position wherein it holds the hammeroperating levers 60 and 61 cocked or set against the tensions of their springs 71, 72, includes a set of cams 80 and 81 (Fig. fast on the usual printer drive shaft 82, journaled in the side frames 32 and 83 (Fig. 8) and actuated from a main drive shaft in a manner not shown, to make one complete rotation in counter-clockwise direction, at each operation of the machine.

The cams 80 and 81 coact, respectively, with rolls on the respective arms of a bell crank lever 84 fast on one end of a short shaft 85 jo-urnaled in the side frames 32 and 83.

An arm 86 fast on the short shaft 85 near its opposite end, carries a stud 87 projecting therefrom through a slot 88 (Fig. 1) in the side frame 32, a link 89 connecting the stud 87 with an arm 90 (Figs. 1, 5 and 8) fast on one end of the shaft 68 to which the arms 66, 67 of the restraining and restoring bail 65 are secured.

Obviously, the printer drive shaft 82 and cams 80, 81, when rotated, will rock the bell crank 84 and through the linkage described, will rock the shaft 68 and the restraining and restoring bail, first clockwise to withdraw the hail from the inclined arms 69 and 70 of the hammer-operating levers 60 and 61 to enable the latter to operate, and then in counter-clockwise direction to cause the bail 65 to restore the hammer-operating levers to and hold them in cooked or set positions.

, The cam 80 may be reterredto as the restoring and restraining cam and the cam 81 as the releasing cam,the contour of this latter cam being such as to control the releasing operation of the restraining and restoring bail: 65 in such manner as to cause it to make-three distinct steps from its normal position, shown in Figs. 1 and 3 to 5, to its completely withdrawn position,-shown in Fig. 6, and to this end, the cam 81 is provided with a short dwell 91 (Fig. 5) between its first and second rises, and with a somewhat longer dwell 96 between its second andthird rises,.

after which, the cam 80 becomes effective to restore the bail 65 to its normal position.

It will be remembered that normally, with the restraining and restoring bail 65 in efiective position, (Figs. 1 and 3 to 5), the free ends of the hooked detents 7 8, 7 9 take under theends of the longer arms of the hammeroperating elbow levers 60 and 61, but that the restraining and restoring bail 65 relieves these .detents of thepressure of thehammer-operating levers,sovthat a slight clearance is left between the ends ofthe latter and the hooked detents 78, 79.

A dwell 910 on the release cam 81, maintains the restraining and restoring bail 65 inactive, to afford sufficient time to enter the set up amount in the machine and to set the type-carriers30, after which a cam rise 911 on cam 81 operatesthe linkage to withdrawn the restrainingand restoring bar 65 from the hammer-operating lever. arms '69, 70.

The purpose of the first step of travel of the restraining and restoring bar 65 in its withdrawal from the inclined arms 69 and 70 by their respective detents 78, 79, for individ ual operation. Therefore, theshortdwell 91 of the releasing cam 81 becomes effective to hold the restraining and restoring bail 65 atFthe end of its first step of movement. The second cam rise 912 next becomes effective to impart the second step of movement to the bail 65 to enable the first printing operation to take placein a manner shortly to be eX- plained. y

The longer dwell 96 becomes effective immediately subsequent to the first printing impression, and to the second step of movement of the restraining and restoring bail, to hold the bail ineffective and afford time within which to advance the record material to present a new line to the printing point, after which the cam rise 913 on the release cam 81 operates the restraining and restoring bail the inclined arms 69 and 70 of the hammeroperating levers 60 and 61, and rocks the latter back to their cocked or set positions, against the tensions of the drive springs 71 and 7 2. I

It will be recalled that one of the important objects of this invention is to eiiect a plurality of printing impressions'during a single bers 60 and 61, and independently-operable detents 7 8 and 79 associated therewith, and

arranging to trip the detents successivelyto enable the hammerea'ctuating members to operate successively, means other than the regular reset-ting means being provided to re tract the hammer subsequently to the first imprint, to enable it to deliver. the second impression blow.

As one convenient meansto attain these results, the restoring and restraining bail 65 is utilized to trip the independently-operable detents7 8, 79 successively with a slightinterruption between, provided by thedwell 96 of the cam 81 in the following manner.

Shortly after the beginning of the operation of the machine, the cam 81 (Fig. 5) operates the bell crank 8a and connected linkage to withdraw therestraining and restoring bail 65 one step from its normal posi- .tion, in which normal position it holds the hammer-operating levers 60 'a-nd61 in their 7 fully retracted positions. V

The drive springs 71, 72 cause the operating levers to follow the retractingbail 65 until the ends ofthe longarms of the levers are arrested bythe individual detents T8,

' 7 9. This results in substituting an individual control of the hammer-operating levers, ex-

bail 65 over the hammer-operating levers 66 and 61.

step of movement due to the dwell 91to afford time within which the machine can complete its functions, whereupon the releasing cam 81 again withdraws. the restoring bail 65 one step to trip the detent? 8 to effect the first imprint.

The detents 78 and 79 are each provided with a shoulder 92 and 93, respectively, which lie in the path of the bail 65 on its clockwise or withdrawing movement, and in order to efiect successive hammer impressions, the shoulder 92 on the detent 78 is arranged in advance of the shoulder 93 on the detent 79 so as to be struck by the bail- 65 during its second step of retreat, such second step being of such length, under control of the cam The restoring bail 65 remains in its first '81, as to fall short of striking the shoulder positively displaces the detent 78 to release the hammer-operating lever 60 to the action of its spring 71, which immediately rocks said lever sharply counter-clockwise to drive the hammer into contact with the types on the type carriers 30 in order to take an impression therefrom, as at A on the record material 20 (Fig. 2) inserted in the chute 31 (Fig. 1). The counter-clockwise travel of the hammer-operating lever 60, under the influence of its spring 71, is limited by contact of the inclined arm 69 of the lever with a spacing collar 94 (see dotted lines, Fig. 6) surrounding the shaft 68 and which spaces the detents 78 and 79 apart the proper distance.

The impact of the longer arm of the operating lever 60 against the cross bar of the hammer under the stored energy of the spring 71 imparts sufiicient impetus to drive the hammer against the types after the arrest of the hammer-operating lever by the collar 94, such collar bein so positioned as to effect the arrest of the operating lever be fore it has traveled far enough to prevent the retraction of the hammer preliminary to the second imprint.

The slip 20 or other record material (Fig.

2) upon which the impressions are to bemade, is inserted in the chute 31 in such a position that the bottom edge of the slip rests on the bottom of the chute. In this position, the first printing line of the slip lies at the printing point of the types to receive the first impression, illustrated at A (Fig. 2). After the first impression has been made thereon, the slip is fed, as will be described later, to position the second printing line to receive the second printing impression, shown at B (Fig. 2).

After the platen 47 strikes the type to take the first impression therefrom, the spring 52 immediately retracts or draws the hammer upwardly so that the cross rod 53 contacts with the lower edge of the discharged hammer-operating lever 60, in which position (see Fig. 7) it remains until the second impression is made.

The dwell 96 of the cam 81 holds the restraining bail in the position to which it has advanced on its second step, while the hammer is being retracted, and the record material advanced to position the second printing line opposite the types on the type carriers 30.

The bail 65, on its third clockwise step of movement or withdrawal, which step is imparted thereto by the cams 80 and 81 5), strikes the shoulder 93 (Fig. 4) on the detent 79 to displace the detent and release the hammer-operating lever 61 to the action of its spring 72, which immediately rocks the lever sharply counter-clockwise until it, too, is arrested by the spacing collar 94 on the shaft 68. The end of the inclined arm of the operating lever 61 (Figs. 4 and 7) is recessed at 95 to fit over the spacing collar" 94, and afiord the operating lever 61 a farther counter-clockwise travel than is permitted the lever 60, to insure the contact of the operating lever 61 against the cross rod 53 of the hammer for a sufficient length of time to drive the hammer against the types and effect the second impression. After the hammer-operating lever 61 is arrested by the spacing collar, the momentum of the hammer is suiiicient to carry the platen 47 thereof into contact with the type.

After the platen 47 strikes the type to take the second impression, the spring 52 immediately retracts the hammer until the cross rod 53 rests against the lower edge of the operating lever 61, in which positions the parts are shown in Fig. 6.

The cam (Fig. 5) now rocks the restraining and restoring bail 65 counter-clockise to its normal position, as shown in Figs.

and 5. As the bail 65 moves counterockwise, it first withdraws from the shoulders 92 ant 93 of the detents 78 and 79 to elease the detents to the action of their prings 7 6 and 77, which immediately rock the ietents counter-clockwise until the hooked ends thereof strike and are arrested by the extreme outer ends of their respective hammer-operating levers 60 and 61. The bail 65 continues its counter -clockwise restoring movement, picking up the hammer-operating levers 60 and 61 at their discharged positions (Fig. 6) and restoring them to their normal positions (Fig. 5), where the bail restrains said levers until the next operation of the machine.

A a re a Slip feed Just before the first printing impression is made, a feeding and tension device grips the slip 20 to hold it against movement while the impressions are being made, and to feed the slip after the first impression is made, into position to receive the second impression.

To these ends, a cam 100 (Fig. 1) fast on the printer drive shaft 82, operates a pitman 101, one end of which is pivoted to the arm 102 of one of a pair of drive segments 103 and 104 (Figs. 1 and 8) fast on a shaft 105, supported in the side frame 32 and in the bracket plate 33, to rock the drive segments and shaft in clockwise direction. The drive segments 103 and 104 mesh with and turn gears 106, only one of which is shown, secured to feed cams 108 and 1.09 pivoted on studs 110 and 111 in the side frames 32 and 33 adj acent the opening 48 in the chute 31.

Normally, the peripheries of the feed cams 108 and 109 (Figs. 1 and 8), which peripheries 1 eration of the machine, the drive segments 103 and 10%, on their clockwise travel, rotate the gears 106 and the feed cams 108 and 109 in counter-ciockwise direction to enter the knurled edges of the cams into the chute 31" through the opening 418 to position them opposite a pair of tension rolls 115 and 116 (Figs. 1, 9 and 10), rotatably mounted on arms 117 and 118, pivoted on a shaft 119 j ournaled in the side frame 32 and in a bracket 120.

Springs 121 and 122 (Fig. 9), coiled about the opposite ends of the shaft 119 in opposite directions, each have their inner ends anchored in collars 123 and 12 1, respectively, fast on the shaft 119, the outer ends of the springs operating to press the tension roll supporting arms 117 and 118 against ears 125 and 126 on tensioning arms 127 and 128, respectively, faston the shaft 119. The tension roll 116 normally rests on a collar 129 surrounding the nested sleeves 130, the outer ends of which carry the type wheels 30, which collar limitsthe retracting travel of the tension rolls 115,116.

After the cam 100 (Fig. 1) has shifted the feed cams 108 and 109 through the opening 48in the chute 31 into position to contact the inserted record material 20, a pair of cams 131 and 132 (Fig. 10) fast on the printer drive shaft 82 cooperates with the respective arms of a bell crank 133 jonrnaled on the a short shaft85 previously mentioned, torock the bell crank 133 in clockwise direction. A link 134: connects one arm of the bell crank 133 with an arm of another bell crank 135 pivoted on a rod 136' supported in the side frame 32 and in thebracket 120, whereby the clockwise movement of the bell crank 133 is transmitted to the bell. crank 135 to rock this bellcrank also in clockwise direction. The bell crank 135 on'its clockwise travel, raises a link 137 pivoted at one end to the remaining arm thereof,:the opposite end of the link 37 being slotted to embrace a stud 138 on the tension arm 128 fast on the tension roll supporting shaft 119. On the first part of its upward movement, theslot140 in the link 137 slides idly over the stud 138 in the tension arm 128, until the lower end wall of the slot 140"contacts the stud 138 and rocks the tension arm 128'and shaft 119 connected ment of the tension roll-supporting arms 117 and 118 is arrested. Butthe cams 131 and 132 continue to advance the link 137 for a short distance, thereby rocking the tension arms 127 and128 farther in clockwise direction, to place additional tension on the springs 121 and 122, as a result of which,

the springs press the rolls 115 and 116 more firmly against their feed cams 108 and 109 to grip the inserted record material between them and hold it against movement. 1 The tension rolls swing in a direction substantially radially, relatively to the feed cams 108, 109 to avoid displacement of the record material.

Shortly after the first impression is made on the inserted record material, the cam 100 (Fig. 1) again rocks the shaft 105 and the.

feed cams 108 andl09 counter-clockwise,- and since the tension rolls115 and 116 are now pressing the record material against the knurled peripheries of the feed cams, these feed cams feed the record material to bring the second line thereon into position to .receive the second printing impression.

After the second impression has been made 7 p on the record material, the cams 131 and 132 restore the tension rolls 115 and 116 to their normal positions (Fig. 10) and at about the same time, the cam returns thevfeed cams 108 and 109 clockwise to their normal positions (Fig. 1), thus releasing the inserted record material in the chute 31, so that it may now be removed manually by the operator.

The withdrawal of the tension rolls 115 V and 116 to idle positions is effected by gravbodiment herein disclosed, for it is suscep tible of embodiment in various forms all coming .within the scope of the claims. which follow.
